To aZZ whom it may concern.-

Be'it known that I, KARL KIEFER, a citizen of Germany, residing atCincinnati, in the county of Hamilton, in the State of Ohio, haveinvented'a new and useful Bottle-Stopper, of which the following is aspecification.

My invention relates to the class of bottlestoppers which have theirfastenings on the rim of the bottle-neck. There is no special necknecessary for this device. It is also unnecessary to have it permanentlyfastened to the bottle; but it can be detached like any other stopper.The stopper can be used for any ordinary liquid, filled withoutpressure, but is especially adapted to glass bottles with higher thanatmospherical pressure, where the common cork is apt to leak.

In the drawings the device is shown in different positions. There isalso one construction shown to overcome the difference in the size ofthe bottle-necks.

Figures 1, 2, 3, and 4 show the bottle-stopper, for which it is supposedthat all bottlenecks are blown alike. Fig. 5 shows an adjustablebottle-stopper, which can be fitted to most all bottles with rims. Fig.1 shows the stopper put on a bottle and ready to be closed. Fig. 2 showsthe stopper in closed condition. Fig. 3 is a view from the top of theopened stopper. Fig. 4 shows the diagram of the opened and closedstopper.

Similar letters refer to similar parts throughout the several views. gThe stopper consists ofthe following parts, Fig. 8: The cap a, whichincloses a gasket 19, the four bars 0, and the swallow-tailed sides :1.The one end of the bars 0 is riveted to the cylindrical part of cap a,and the other ends are connected with side parts at by the long rivetse, forming hinges. Each pair of bars a, fastened to one side part (i andconnected in the described way to cap a, act as levers on thediametrically-opposed sides of the bottleneck.

The stopper is put on in the following manner: The cap a is brought inthe right position and the two sides are put below the rim, as shown inFig. 1 in view and Fig. 4 in the diagram. A pressure on hinges e and eis now exerted syn chronically. The knee-levers, composed out of bars 0and side bars d, will soon cover each other, at which moment thegreatest pressure is exercised. In order to secure a permanent remainingin this condition it is necessary to let the levers go over this pointuntil the hinges 6 come in contact with the bottle-neck. In thisposition they will remain by themselves.

The gasket 17 can be manufactured either out of cork-Wood or rubber, orboth combined, according to the pressure in the bottle. Theswallow-tailed parts of the side parts cl are bent according to thebottle-neck, as shown in Figs. 1 and 2. v

In Fig. 5 the cap has an aperture 011 its top and a set-screw g. On theprojection 2' of this screw a plate is is loosely riveted. The gasket 1)is now put against this plate 70, which can be lowered and raised bymeans of this setscrew g to suit the height of the bottle-neck.

What I do claim as my invention, and. desire to secure by LettersPatent, is

1. The combination of a cap, a gasket, and

two or more symmetrical sets of self-locking levers, and consisting ofthe bars 0 and the side d, and pivotally connected to the cap, whichexert on opposite'sides of the bottleneck a pressure upon the cap, underan angle to the axis of the bottle, sufficiently large to prevent theirslipping from a ring-shaped projection of the bottle.

2. The combination of a cap, a gasket and two or more symmetrical setsof self-locking levers, and consisting of the bars 0 and the side d, andpivotally connected to the cap, which exert on opposite sides of thebottleneck a pressure upon the cap, under an angle to the axis ofthe'bottle, sufficiently large to prevent their slipping from aring-shaped projection of the bottle with means allowing the furthertightening of the gasket, after the same has been locked to the bottlemouth.
